Definitions

  • the present invention relates to the use of the compound escitalopram (INN-name), i.e. (S)- 1 -[3-(dimethylamino)propyl]- 1 -(4-fluorophenyl)-l ,3-dihydro-5- isobenzofurancarbonitrile, or a pharmaceutically acceptable salt thereof for the preparation of a medicament for improving cognition in a condition where the cognitive processes are diminished.
  • escitalopram i.e. (S)- 1 -[3-(dimethylamino)propyl]- 1 -(4-fluorophenyl)-l ,3-dihydro-5- isobenzofurancarbonitrile
  • Escitalopram is the (S)-enantiomer of the following structure:
  • Escitalopram is now marketed as an antidepressant and for the treatment of generalised anxiety disorder (GAD), panic disorder (PD) and social anxiety disorder (SAD).
  • GAD generalised anxiety disorder
  • PD panic disorder
  • SAD social anxiety disorder
  • WO0103694 discloses the use of escitalopram for the treatment of neurotic disorders.
  • ADHD attention deficit hyperactivity disorder
  • Parkinson's disease mild cognitive impairment
  • MCI Alzheimer's Disease
  • Alzheimer's Disease dementia
  • anxiety anxiety
  • age associated memory impairment Alzheimer's Disease or post-traumatic stress disorder
  • patients taking benzodiazepines or tricyclic antidepressants and in a range of neurodegenerative diseases in addition to Parkinson's Disease and Alzheimer's Disease.
  • Diminished cognitive processes refer to the difficulties with attention, learning, memory and executive function (relevant reactions to external stimuli). These can include: deficits in attention, disorganized thinking, slow thinking, difficulty in understanding, poor concentration, impairment of problem solving, poor memory, difficulty in expressing thoughts and/or difficulty in integrating thoughts, feelings and behaviour and extinction of irrelevant thoughts as well as attention and vigilance, verbal learning and memory, visual learning and memory, speed of processing and social cognition.
  • VTA ventral tegmental area
  • fluoxetine, citalopram, paroxetine, sertraline and fluvoxamine all may cause a slight inhibition of the firing rate of mesocorticolimbic dopaminergic neurons in the VTA (Prisco and Eposito, 1995, Br J Pharmacol 116:1923-31; Di Masico et al, 1998, Brain Res Bull 46(6): 547- 54, suggesting that these compounds cannot be used in improving cognitive processes. Moreover it has been reported that citalopram as adjunctive therapy to atypical antipsychotic treatment produces no significant cognitive improvement in patients with schizophrenia (Friedman et al, 2005, J. Clinical Psychopharmacology, 25(3), 237-42).
  • NRI selective noradrenaline reuptake inhibitors
  • reboxetine enhances the excitability of dopaminergic neurons in the VTA with a preferential activation of their burst firing mode (Linner et al, 2001, JPET, 297(2):540-9) and administering of reboxetine has been suggested to have some beneficial effect in the treatment of ADHD.
  • APD atypical, but not typical, antipsychotic drugs
  • Drugs approved for Alzheimer's dementia also have some effect on diminished cognitive processes, but work via completely different mechanisms, reflecting that cognition problems can have very different pathology, such as acetylcholinesterase inhibitors like donepezil, rivastigmine and galantamine.
  • Memantine has weak NMDA antagonistic properties which gives a more "physiological" antagonism of too much background excitation, whereby it increases the signal to noise ratio on glutamate activity.
  • EP 474580 discloses that citalopram is useful in the treatment of cerebrovascular disorders and the brain damage and the impairment of memory functions in connection therewith, and that it shows inhibiting action on platelet aggregation. Furthermore EP 474580 suggests that citalopram has an anti-amnesic effect and improves cognitive function in elderly depressed patients having concomitant dementia. It is mentioned that the optical isomers of the compounds may also be used. The effect mentioned in this disclosure suggests a neuroprotective role. Accordingly there is a significant unmet medical need for therapies, which can improve the cognitive symptoms in various diseases and disorders and/or have lowered side effects as compared to known treatments of cognitive symptoms.
  • Escitalopram has now been found to increase the firing rate of dopamine cells in the VTA, to stimulate the glutamate-driven burst firing in VTA and to facilitate NMDA- induced currents.
  • the present invention relates to the use of escitalopram or a salt thereof for the preparation of a medicament for improving cognition in a condition where the cognitive processes are diminished.
  • the present invention relates the use of escitalopram or a pharmaceutically acceptable salt thereof in combination with one or more antipsychotic agents for the preparation of a medicament for improving cognition in a condition where the cognitive processes are diminished.
  • the present invention relates the use of escitalopram or a pharmaceutically acceptable salt thereof for the preparation of a medicament to be used in the adjunct treatment with an antipsychotic agent for improving cognition in a condition where the cognitive processes are diminished.
  • the present invention relates to a pharmaceutical composition
  • a pharmaceutical composition comprising escitalopram or a pharmaceutically acceptable salt thereof and one or more antipsychotic compounds for improving cognition in a condition where the cognitive processes are diminished.
  • the present invention relates to a method of improving cognition in a condition where the cognitive processes are diminished comprising administering escitalopram or a pharmaceutically acceptable salt thereof.
  • FIG. 2 Escitalopram stimulates the glutamate-driven burst firing in VTA dopamine cells in vivo more potently than citalopram and R-citalopram blocks the effect of escitalopram.
  • Figure 3 Effect of risperidone (atypical antipsychotic), citalopram, escitalopram, and reboxetine (NRI) on NMDA-induced currents in pyramidal cells of the medial prefrontal cortex in vitro.
  • a novel use of escitalopram or a pharmaceutically acceptable salt thereof, namely for the preparation of a medicament for improving cognition in a condition where the cognitive processes are diminished is provided.
  • escitalopram increases the firing rate of dopamine cells in the VTA in vivo, an effect blocked by R-citalopram. Additionally it has been found escitalopram compared with citalopram more potently and also dose-dependently stimulates the glutamate-driven burst firing in VTA dopamine cells in vivo, an effect that is blocked by R-citalopram. Moreover it has been found that escitalopram and reboxetine but not citalopram facilitate NMDA-induced currents in pyramidal cells of the medial prefrontal cortex in vitro.
  • the present findings indicate that escitalopram in similarity with NRIs, such as reboxetine, enhance the excitability of the dopaminergic system. Additionally the present findings indicate that escitalopram in similarity with atypical, but not typical antipsychotic drugs, as well as reboxetine facilitates prefrontal glutaminergic neurotransmission.
  • escitalopram can be used for improving cognition in a condition where the cognitive processes are diminished as well as augmenting the response to exposure therapy. Additionally the present findings also strongly suggest escitalopram may be used as adjunct treatment to typical antipsychotic drugs for improving cognition in a condition where the cognitive processes are diminished and in the treatment of schizophrenia and other related diseases and disorders.

  • the effects of the drugs or drug combinations on the NMDA-induced currents were calculated by dividing the NMDA-induced currents after the bath application of the drugs by the control NMDA-induced currents. The results shown in the figure are presented as mean ⁇ S.E.M.
  • Figure 1 describes the effect of citalopram and each of its enantiomers on firing rate of dopamine cells in the VTA. It is shown that citalopram at the tested doses (0-1280 ⁇ g/kg) does not increase the firing rate. On the other hand escitalopram elevates firing rate statistically significant at 320 ⁇ g/kg and this effect appears to be maintained at the higher dose (640 ⁇ g/kg). Furthermore it is shown that the firing rate is unaffected by R-citalopram and that the effect of escitalopram (320 ⁇ g/kg) can be blocked by pre-treatment with 320 ⁇ g/kg of R-citalopram, thus further substantiating that this effect is specific to escitalopram.
  • Figure 2 describes the effect of citalopram and each of its enantiomers on burst firing of the dopaminergic cells recorded in the in the VTA. It was shown that escitalopram increases burst firing statistically significant dose-dependently at doses equal to and above 160 ⁇ g/kg. At the highest dose tested (640 ⁇ g/kg) escitalopram causes a burst difference of about 20%. Citalopram also appear to increase burst firing, allthough this only reaches significance at the 640 ⁇ g/kg dose, and the maximal response appears to be approximately 10% burst difference. Further it is shown that R- citalopram alone has no effect on burst firing and that R-citalopram (320 ⁇ g/kg) significantly inhibits the effect of escitalopram (320 ⁇ g/kg).
  • Figure 3 describes the effect of risperidone (atypical antipsychotic), citalopram, escitalopram and reboxetine (NRI) on NMDA-induced currents in pyramidal cells of the prefrontal cortex. It has previously been shown that atypical antipsychotics increase NMDA-induced currents in this preparation. This is examplified by risperidone. It is shown that reboxetine (NRI) but not citalopram (SSRI), nor fluoxetine (data not shown) increases NMDA-induced currents. Surprisingly escitalopram facilitates the NMDA-induced currents to similar extent as the risperidone and reboxetine. It is furthermore shown that this effect is likely mediated through the dopamine Dl receptor as a dopamine Dl receptor antagonist (SCH 23390) reverses the effect of escitalopram.
